MATTRESS-SUPPORT.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed June 1,1906. Serial No. 319,692.

T0 61/ 1072,0112 it may concern.-

Be it known that I, J OI-IN S. JOHNSTON, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Mattress-Supports, of which the following is a specification.

This invention relates to a novel and useful construction for a bed-frame, having for its object the provision of effective means for supporting a wire mattress at the ends of the bed-frame and holding it taut and firm.

The invention consists, essentially, in

brackets or supports for carrying the ends of the wire mattress, those at one end being adjustable, so as to permit the mattress to be tightened and securely held, and all of the brackets or supports being adjustable at the sides of the bedframe for a like purpose and the invention also comprises numerous details and peculiarities in the construction, ar rangement, and combination of parts, substantially as will be hereinafter described and claimed.

v In the accompanying drawings, illustrating my invention, Figure 1 is a side elevation of my improve d wire -mattress-supp orting me ohanism. Fig. 2 is a top plan view of the same arranged in position on a bed-frame. Fig. 3 is a detail view of the pivoted member of one of the brackets employed for tightening the mattress. Fig. t is a detail view of the stationary member of the same bracket or support.

Similar numerals represent corresponding parts throughout the figures of the drawings.

My improved. wire-mattress support is intended and adapted for use with any kind of bed-frame, and I do not wish to be limited to any model or variety thereof; but, speaking generally, such aframe maybe said to consist of horizontal side rails 1 1, connected together at the head and foot by means of the transverse connecting-rails 2 2, there being at the four corners of the frame the customary posts 3 3, which sustain the frame in the required position of horizontality. It is unnecessary to explain any of the other accessories of the frame beyond saying that the side rails 1 1 are intended and adapted to sus-.

tain the weight of a mattress-frame thereon.

The parts of my improvements for carrying the wire mattress consists, essentially, of four brackets carried by the side rails 1 1, two of said brackets being secured to the rails near one end of the bed in a fixed position,

though they are adjustable when required, while the other two brackets are fastened to the side rails near the other end of the bed and are likewise adjustable on the rails when required; but these brackets differ from the first two in that they are furnished with pivoted arms.

4 4 denote the two stationary brackets consisting of upwardly-extending arms 4 and a base portion 5, provided with a groove 6, which receives the side rail 1, so that the bracket may be securely fastened to said rail at the desired point by means of a set-screw, belt, or other similar clamping device 7. The upper end of the arm 4* is formed with a horizontal face 8, alongside of which is an angular shoulder 9. Two brackets of this kind are secured to the rails 1 near one end of the bedframe, preferably the foot, as shown in Fig. 2, said two brackets being of the same pattern and form, except that they are preferably made rights and lefts, so that the grooves 8 may pass over the rails 1 from the inside of the bed instead of from the outside of the rails, this preferably being the method of combining the parts to the best advantage.

10 designates an angle-rail 6, secured to the two stationary brackets 4 by being bolted, screwed, or otherwise fastened in a horizon tal position upon the flat surfaces 8 at the upper ends of the brackets 1, and said anglerail 10 has firmly fastened to the horizontal depending ledge thereof one end of the wire mattress 11. At the other end of the bed, preferably the head end, I employ another pair of brackets which differ somewhat in construction from the first-mentioned pair, said brackets being designated by the reference-numeral 12 and consisting each of a base portion 13, having a groove 14, by means of which the bracket is seated on the side rail 1 in like manner as brackets 4 are seated on the side rail, being securely fastened there by means of set-screws or bolts 15. These brackets 12 also have pivoted arms 16, which are pivotally secured at 17 to the base portions 13. (See Fig. 1 and also Figs. 3 and 4.) The upper ends of the arms 16 are provided with flat surfaces 18, alongside each of which is a shoulder 19, and said surfaces 18 support the angle-rail 20, to the vertical depending part of which is secured the other end of the wire mattress 11, whose first end we have seen is fastened to the angle-rail 10, carried by the upper arms of the other pair of brackets. The angle-rail 20 is held firmly upon the surfaces 18 by means of screws or bolts 21. Thus it will be seen that one end of the wire mattress is carried bya pair of movable arms, said arms-moving in parallel vertical planes and on pivots similarly related to the side rails of the bedframe, so that the mattress 11 can be tightened or loosened by properly moving the arms. In order to provide a lock for securely fastening the arms 16 in position after the mattress has been stretched to make it sufficiently taut and firm, I provide the lower ends of the arms 16 at points adjacent to the pivotal point 17 with dogs 22, which fall into and engage with recesses 23 on the adjoining face of the base 13. Both of the movable arms 16 are thus provided with 1ocking-dogs dogs 22 with the notches 23 will take place.

In first placing not only the stationary brackets, but the pivoted ones, regard will be had to the length of the wire mattress, and hence the brackets will be fastened to the side rails 1 at the proper points from the foot and head of the bed, for it must be remembered that the extent of movement of the pivoted arms in their vertical planes in acting on the mattress to tighten the same is comparatively small, and hence said brackets must be so located with reference to the end of the bed as to permit its movement to properly take place.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a bed-frame and a mattress, of a pair of supports adjustable on the side rails of the frame near one end of the bed, a rail connecting said supports to which rail one end of the mattress is attached, a

pair of pivoted supports adjustablycarried on the side rails of the frame near the other end of the bed, a rail connecting said pivoted supports to which rail the other end of the mattress is attached, and locking mechanism for locking the pivotal supports at certain points in their pivotal movement so as to the'side rail of the frame, and provided with give the mattress the proper tension.

2. The combination with a bed-frame and a mattress, of a pair of supports adjustable on the side rails of the frame near one end of the j bed, a rail connecting said supports to which rail one end of the mattress is attached, a pair of pivoted supports adjustably carried j on the side rails of the frame near the other end of the bed, a rail connecting said pivoted supports to which rail the other end of the. f mattress is attached, and locking mechanism for locking the pivotal supports at cer- 5 tain points in their pivotal movement so as to give the mattress the proper tension, said locking means consisting of interlocking faces on theinterpivoted parts of the pivotal supports.

3. The combination with a bed-frame and a mattress, of a pair of stationary brackets each having a grooved base and being seated in'a stationary position on the side rails of the frame near one end of the bed and provided with set-screws to permit adjustment at times, a rail connecting said brackets to which rail one end of the mattress is attached, and a second pair of brackets or supports consisting of interpivoted members, the bottom member of each being grooved and applied to the side rail of the frame near the other end of the bed, and said interpivoted mem-' bers having dog-provided interlocking faces, and a rail connecting the latter supports with each other to which rail the other end of the a grooved and applied .to the side rail of the frame while the upper member is movable on the pivot for making taut the mattress, a flanged rail secured to the movable portions of the latter pair of brackets to which rail the other end of the mattress is secured, and means operating automatically for holding the movable portions of the latter brackets in proper position after the mattress has been stretched taut.

5. In a mattress-support, the combination with a bed-frame and a mattress, of a pair of supports each having a grooved base to receive the side rail of the frame and provided with a retaining-screw, a rail connecting the upper ends of said supports to which rail the mattress is attached, and a second pair of supports at the other end of the bed, each consisting of a movable member and a base member to which it is pivoted, said base member being grooved soas to be applied to clamping means, a rail connecting the movable portions of the two brackets to which rail the other end of the mattress is attached,

and 'means for holding stationary the mov- May, 1906.
